It depends on how bad your vision is.
If it is 20/400 as mine was, after 18 years my vision is still clear tho I'm probably down to 20/40 from 20/20. I don't wear glasses or contacts and haven't since the operation.
I was unable to scuba dive, down hill ski, play racquet ball, and playing ultimate frisbee was impossible when the humidity was high.
When I went to the ocean- I had to leave my glasses on the beach so everything was a blur.
I experimented with disposable contacts and they were fair.
Lasik cost me $500 ($250 per eye) and it took 32 seconds and 39 seconds for my left and right eyes.
If it is dry and I don't drink enough water my eyes will turn fuzzy until I rehydrate. Eyedrops usually fix it instantly but sometimes not.
The surgery gave me a tremendous amount of freedom.
Their status page promised roll-outs starting in late 2012, but it also has horrifically bad information, even for an ISP ("Verizon will use a IPv6/56 address format, which means this will support 56 LANs.") I've asked about it several times, but no one at any level seems to know what's going on. The routers have been IPv6-enabled since spring of 2013, which got a lot of people excited. There's a rumor that the hold-up has to do with newer set-top boxes and broken IPv6 stacks, but no one knows how believable that is. (I don't buy it. I just think Verizon is refusing to spend the money necessary to implement it.)
I agree, we shouldn't be subsidizing the green industries, instead we should just regulate the shit out of the extraction industries which manage to externalize so much of their costs.
How much should the coal industry pay for the ~1M deaths/year?
Sounds like my case. Increasing couldn't get wear contacts any more without problems, hated all of the problems of glasses, was scared of the surgery... and it was just nothing. Seriously, how can instantly improved vision not be at the top of your to-do list?
Where are you that 20/90 is legally blind? That's nothing.
In my state it's 20/200. You need glasses past 20/40 if you want to drive, though.
You don't have to login to use a Chromebook, you can browse as a guest. As to your comment about compilers, MS offers Visual Studio Online Basic for free.
Hand me the circle you say "exists".
You explore that shit.
I dig girls.
Define a circle.
Do circles exist in reality, or only in mathematical models?
What do engineering artifacts, as approximations of circles, bear in relation to "real" circles?
Are infinities actual, or are they mathematical descriptions for mental extrapolations based in observed phenomena?
Do mathematical models display consistency with real, observable phenomena or with any mental extrapolation? Which one is more "real"? Why?
Mathematics can only describe the set of perceptions, IMHO. When they describe unperceived "realities" they enter the realm of fictions or metaphysics.
Except Google doesn't track apps for education users.
That's probably a good thing since students shouldn't be static consumers of information and tablets are really subpar for most kinds of content creation. Add in the fact that a Chromebook costs half as much as even an ipad mini and overall the schools are probably making the rational choice.
I'm up around retirement age. My eyes don't chage focus much at all. So I have to swap lenses to go from distance to close-up vision. (Yes I could use some kind of bi/tri/progressive-focal lenses. But at the moment swapping is adequate for me.)
Until they find a way to correct presbyopia (and they don't see to be even researching it), I'd still have to don/remove glasses anyhow. With my extreme astigmatism, extreme nearsightedness, and substantial age, I'm not a good candidate for lasic and stand a substantial chance of visual artifacts from it. I'm also a target shooter, so my glasses double as eye protection.
Given all this, the potential benefits for me would be small and the risks and cost oughtweigh them.
But if they ever find a way to fix presbyopia the equation could change substantially.
